Piraeus

On November 21st 2008 ATTIKO METRO S.A. proceeded to the re-procurement of the project related to Line 3 Metro extension to the Western Suburbs, terminating in the area of Piraeus (underground tunnel, 7.6 km long, with 6 modern stations: Aghia Varvara, Korydallos, Nikaia, Maniatika, Piraeus, Dimotiko Theatro).

On February 13th 2009, 6 technical consortia/joint ventures expressed their interest in the construction of the project. On October 5th 2011, ATTIKO METRO S.A. proceeded to the unsealing of the Financial Offers for the Project concerning the extension of Metro Line 3 to Piraeus.

The classification order of the three bidding joint ventures, based on their Financial Offer, is as follows:

JOINT VENTUREFINANCIAL OFFER
1. J&P – ΑVΑX ΑΕ – GHELLA SPA – ALSTOM TRANSPORT SA343.96 million €
2. AKTOR ΑΤΕ – ΤΕRΝΑ ΑΕ349.00 million €
3. FCC CONSTRUCCION S.A. – ALPINE BAU GMBH349.75 million €

Based on the aforementioned Tender results, J&P – ΑVΑX S.A. – GHELLA SPA – ALSTOM TRANSPORT SA is the lowest-bidder of the Tender.

On March 1st 2012, the relevant contract was signed with the contracting joint venture J&P – AVAX S.A., GHELLA SPA, ALSTROM TRANSPORT S.A for the construction of Line 3 extension from Aghia Marina to Piraeus, 7.6 km long in total, with 6 modern Metro Stations. Attiko Metro S.A. was represented by Mr. Christos Tsitouras, Chairman of the BoD and Managing Director, while the Construction Joint Venture J&P ΑVAX SA was represented by Mr. Konstantinos Mitzalis, Managing Director.

This Project constitutes a 730,000,000 EURO investment in areas of Piraeus Municipalities and other Municipalities in the wider area (Nikea, Korydallos, Aghia Varvara), which are currently faced with acute traffic problems and sub-standard services, in terms of Public Transport Modes.

The Metro Extension to Piraeus will serve approximately 132,000 passengers on a daily basis, while the distance between the Port and the International Airport will be covered by the Metro in just 45 minutes. Additionally, once the Metro becomes operational, the number of vehicles will be reduced by approximately 23,000 on a daily basis, leading to a respective daily reduction in CO2 by 120 tn.

Especially as regards Piraeus Station, a major Transportation Junction will emerge, connecting the two Metro Lines (Line 1 and Line 3), the Port, the Suburban Railway and the Tramway, which is also foreseen to pass through the same area, providing, thus, inter-modal transfers.

The Metro tunnel will be constructed using a Tunnel Boring Machine (TBM) in order to minimize the inevitable disturbance to the functions of the Municipalities; during the construction period (2012-2017) 2,000 persons in total are foreseen to be employed in this Project.

The extension of the Tramway from Neo Faliro to Piraeus centre recently commenced, completing, thus, the direct connection of the coastal axis with Piraeus through the Tramway network. More specifically, in January 2013 the contract was signed between ATTIKO METRO S.A. and the Company THEMELI S.A.

Apart from the Line 3 Extension to Piraeus, ATTIKO METRO S.A will shortly be engaged in the following projects as well, namely:

  1. Extension of the Tramway network from Neo Faliro to Piraeus centre, completing, thus, the direct connection of the coastal axis with Piraeus through the Tramway. The construction of this specific project commenced in September 2013 by ATTIKO METRO.
  2. Conversion of Line 1 (ISAP) section form N.Faliro to Piraeus into an underground structure, with the addition of one new station in the area of Keranis Factory, unifying, in terms of functions and town planning the areas of Piraeus currently served by the surface ISAP Line 1. The designs pertaining to this Project are about to be completed enabling, thus, ATTIKO METRO S.A. to put it to Tender.
  3. Extension to the Tramway Network to Keratsini – Perama, following an underground alignment at a large part of Keratsini Municipality, running along the alignment of the old Perama tramway. The Advanced Concept Designs regarding this Project are underway.
